McMahon John #6
Guadalupe County · LA Vernia field · NO Production · Vertical
Mcmahon John #6 (API 42-187-31586) is a well in Guadalupe County operated by J.A.G. Oil & Gas, completed August 25, 1981 and listed as no production on the RRC schedule.
The RRC has issued one drilling permit, issued April 30, 1981, permitted to 900 ft.
It was permitted by Supreme Oil Company and has since transferred to J.A.G. Oil & Gas on the wellbore schedule.
Completion filings report 2 formation tops, including Green Sand, Navarro.
Its lease has reported 12.6K barrels of oil and 89 mcf of gas since January 1993, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Supreme Oil Company; the EWA schedule now lists a different operator.
